Mechanical component and timepiece

A timepiece comprising:

• an axle;
• a rotary member that has a web arm which engages the axle, the rotary member having a rim which has a plurality of teeth;
• and
• a movement barrel operatively associated with the axle and the rotary member,
• wherein the web arm has a spoke which radially extends from the rim and a comb which branches from the spoke,
• the spoke extends in a radial direction from the rim toward the axle, and
• the comb has a cross beam which extends in a direction intersecting the spoke.

A mechanical component for a timepiece comprising:

• an axle;
• and
• a monolithic gear wheel including:
• a plurality of radial web arms engaging the axle at a plurality of discrete circumferential locations, and
• an annular rim encircling the web arms, the rim having a plurality of gear teeth extending therefrom,
• wherein each web arm includes:
• a spoke radially extending from a proximal end at the rim to a distal end at the axle;
• a plurality of laterally spaced apart cross beams extending from first ends at the spoke in a direction substantially parallel to a tangent of the rim, and
• a spine radially extending from second ends of the cross beams to the axle, a proximal end of the spine being radially spaced apart from the rim.
